DESCRIPTION
The MA4AGSW5 is an Aluminum-Gallium-Arsenide,
single pole, five throw (SP4T), PIN diode switch. The
switch features enhanced AlGaAs anodes which are
formed using M/A-COM Tech’s patented heterojunction technology. This technology produces a
switch with less loss than conventional GaAs processes. As much as a 0.3 dB reduction in insertion
loss can be realized at 50GHz. These devices are
fabricated on an OMCVD epitaxial wafer using a
process designed for high device uniformity and
extremely low parasitics. The diodes themselves
exhibit low series resistance, low capacitance, and
fast switching speed. They are fully passivated with
silicon nitride and have an additional polymer layer
for scratch protection. The protective coating
prevents damage to the diode junction and anode
air-bridges during handling and assembly. Off chip
bias circuitry is required.

Operation of the MA4AGSW5 Switch
The simultaneous application of a negative DC current to the low loss port and positive DC current to the
remaining isolated switching ports is required for the operation of the MA4AGSW5, AlGaAs, PIN switch. The
backside area of the die is the RF and DC return ground plane. The DC return is connected to the common port
J1. The forward bias voltage at J2, J3, J4,J5 & J6 will not exceed ±1.6 volts and is typically ± 1.4 volts with supply
current of ± 30mA). In the low loss state, the series diode must be forward biased and the shunt diode reverse
biased. While for the Isolated port, the shunt diode is forward biased and the series diode is reverse biased. The
bias network design shown below should yield > 30 dB RF to DC Isolation.
Available for use in conjunction with M/A-COM Tech’s line of AlGaAs switches are two, fully integrated, broadband, monolithic, bias networks which may be used as an alternative to the suggested individual component bias
network shown below. Refer to datasheets for the MA4BN1840-1 and MA4BN1840-2 for additional information.
The lowest insertion loss, P1dB, IP3, and switching speed is achieved by using a voltage pull-up resistor in the DC
return path, (J1). A minimum value of | -2V | is recommended at this return node, which is achievable with a
standard, ± 5V TTL Controlled PIN Diode Driver.

ASSEMBLY INSTRUCTIONS
CLEANLINESS
The chip should be handled in a clean environment.
STATIC SENSITIVITY
This device is considered ESD Class 1A, HBM. Proper ESD techniques should be used during handling.
GENERAL HANDLING
The protective polymer coating on the active areas of the die provides scratch and impact protection,
particularly for the metal air bridge, which contacts the diode’s anode. Die should primarily be handled with
vacuum pickup tools, or alternatively with plastic tweezers.
ASSEMBLY TECHNIQUES
The MA4AGSW5, AlGaAs device is designed to be mounted with electrically conductive silver epoxy or with a
low temperature solder perform, which does not have a rich tin content.
SOLDER DIE ATTACH
Only solders which do not scavenge gold, such as 80/20, Au/Sn or Indalloy #2 is recommended. Do not
expose die to temperatures greater than 300°C for more than 10 seconds.
ELECTRICAL CONDUCTIVE EPOXY DIE ATTACH
Use a controlled thickness of approximately 2 mils for best electrical conductivity and lowest thermal
resistance. Cure epoxy per manufacturer’s schedule. Typically 150°C for 1 hour.
RIBBON/WIRE BONDING
Thermo-compression wedge or ball bonding may be used to attach ribbons or wire to the gold bonding pads.
A 1/4 x 3 mil gold ribbon is recommended on all RF ports and should be kept as short as possible for the
lowest inductance and best microwave performance. For more detailed handling and assembly instructions,
see Application Note M541, “Bonding and Handling Procedures for Chip Diode Devices” at
www.macomtech.com.
